driven by the motor, the oil pump of the taper pipe reducer outputs hydraulic oil, which pushes the plunger in the compression cylinder to move forward, so that the plunger and the two inner conical sleeves on the front cylinder cover push the die holder with symmetrical conical surfaces to shrink radially, thus realizing the compression of the rubber hose by the module. When the shrinkage reaches the set value of the scale, the buckle automatically stops, the electromagnetic reversing valve is reversed, the hydraulic oil enters the two mold opening cylinders to push the buckle plunger to move in the opposite direction, and the mold base drives the module to recover under the action of the spring.
Taper tube shrinking machine is a hydraulic full-automatic tube-end processing machine which expands and contracts the end face of pipe fittings under normal conditions and is controlled by an integrated touch display screen. By changing the die, the tube ends of pipe fittings can be expanded, contracted, bulged and upset, and manual, inching or automatic processing forms can be freely decided according to users' needs.
the taper pipe reducer is composed of oil tank, lathe bed, slide block, main oil cylinder, mold core rod (optional), limit oil cylinder, compression oil cylinder, clamping mold, axial positioning oil cylinder and axial positioning angle iron. The working speed of the main cylinder can be adjusted by setting a tubular throttle valve on the loop of the main cylinder; A superimposed hydraulic control one-way valve is arranged on the circuit of the compression cylinder, thus ensuring that the mold does not loosen during clamping; The circuits of the shift cylinder, the limit cylinder and the axial positioning cylinder are all provided with superimposed bidirectional throttle valves, which can adjust the bidirectional movement speed of the above cylinders. Among them, the shift cylinder and the limit cylinder cooperate to use the conversion station, so that the station conversion is convenient and accurate, and the processing quality of the pipe fittings is ensured. Taper pipe shrinking machine is widely used in the processing and forming of pipe fittings, automobile oil pipes, air ducts, water pipes, air conditioning pipes and other connecting parts. It is an ideal pipe end forming equipment, and the processing shapes include: convex, concave, long flat, square, oblique, V-shaped, open elbow, flat elbow and so on.
